In a map with a large number of devices - is there a way to tell netbrain to arrange the icons in a particular way? You can see in the attachment that I have almost a decent semi-circle of leaf switches below four spines. But still looks kind of herky jerky. Any recommendation?

Yes, in IE7.1a, NetBrain provides auto layout manager function which automatically organize map objects based on network infrastructure, sample layout, or geometry. With this function, you can save manual laboring for map layout and it will be more convenient to find or manage devices on a map.
Please kindly refer to https://www.netbraintech.com/docs/ie...yout-style.htm for more details:
The function supports the following types of the map layout.
▪Layout by Tag — organizes devices based on their tags to reflect real network infrastructure, such as the three-layer network hierarchy. To use the layout by tag:
1.Create a Layout Style
2.Apply a Layout Template on Map
▪Layout by Sample — organizes devices based on a sample map. To use the layout by sample:
1.Save a Map Layout as Sample
2.Apply a Layout Template on Map
▪Layout by Geometry — organizes devices based on geometric shapes.

A way to do layers, like you can do in Visio, would be great in NetBrain. That way, you'd be able to select/de-select layers to simplify the map for a variety of purposes. I realize you can do some of that with site manager, but there are limitations.
